API

Generally, every method of the Mathematica bindings that returns a value can throw a Tinkerforge.TimeoutException. This exception gets thrown if the device did not respond. If a cable based connection is used, it is unlikely that this exception gets thrown (assuming nobody plugs the device out). However, if a wireless connection is used, timeouts will occur if the distance to the device gets too big.

Since .NET/Link does not support multiple return values directly, we use the out keyword to return multiple values from a method. For further information about the out keyword in .NET/Link see the corresponding Mathematica .NET/Link documentation.

The namespace for all Brick/Bricklet bindings and the IPConnection is Tinkerforge.*.

Basic Functions

BrickletVoltageCurrent[uid, ipcon] → voltageCurrent
Parameters:
  • uid – Type: String
  • ipcon – Type: NETObject[IPConnection]
Returns:
  • voltageCurrent – Type: NETObject[BrickletVoltageCurrent]

Creates an object with the unique device ID uid:

voltageCurrent=NETNew["Tinkerforge.BrickletVoltageCurrent","YOUR_DEVICE_UID",ipcon]

This object can then be used after the IP Connection is connected (see examples above).

The .NET runtime has built-in garbage collection that frees objects that are no longer in use by a program. But because Mathematica can not automatically tell when a Mathematica "program" doesn't use a .NET object anymore, this has to be done by the program. For this the ReleaseNETObject[] function is used in the examples.

For further information about object management in .NET/Link see the corresponding Mathematica .NET/Link documentation.

BrickletVoltageCurrent@GetCurrent[] → current
Returns:
  • current – Type: Integer, Range: [-231 to 231 - 1]

Returns the current. The value is in mA and between -20000mA and 20000mA.

If you want to get the current periodically, it is recommended to use the CurrentCallback callback and set the period with SetCurrentCallbackPeriod[].

BrickletVoltageCurrent@GetVoltage[] → voltage
Returns:
  • voltage – Type: Integer, Range: [-231 to 231 - 1]

Returns the voltage. The value is in mV and between 0mV and 36000mV.

If you want to get the voltage periodically, it is recommended to use the VoltageCallback callback and set the period with SetVoltageCallbackPeriod[].

BrickletVoltageCurrent@GetPower[] → power
Returns:
  • power – Type: Integer, Range: [-231 to 231 - 1]

Returns the power. The value is in mW and between 0mV and 720000mW.

If you want to get the power periodically, it is recommended to use the PowerCallback callback and set the period with SetPowerCallbackPeriod[].

The default values are 3, 4 and 4 (64, 1.1ms, 1.1ms) for averaging, voltage conversion and current conversion.

The following constants are available for this function:

For averaging:

  • BrickletVoltageCurrent`AVERAGINGU1 = 0
  • BrickletVoltageCurrent`AVERAGINGU4 = 1
  • BrickletVoltageCurrent`AVERAGINGU16 = 2
  • BrickletVoltageCurrent`AVERAGINGU64 = 3
  • BrickletVoltageCurrent`AVERAGINGU128 = 4
  • BrickletVoltageCurrent`AVERAGINGU256 = 5
  • BrickletVoltageCurrent`AVERAGINGU512 = 6

  • BrickletVoltageCurrent`AVERAGINGU4 = 1
  • BrickletVoltageCurrent`AVERAGINGU16 = 2

Advanced Functions

BrickletVoltageCurrent@SetCalibration[gainMultiplier, gainDivisor] → Null
Parameters:
  • gainMultiplier – Type: Integer, Range: [0 to 216 - 1]
  • gainDivisor – Type: Integer, Range: [0 to 216 - 1]

Since the shunt resistor that is used to measure the current is not perfectly precise, it needs to be calibrated by a multiplier and divisor if a very precise reading is needed.

For example, if you are expecting a measurement of 1000mA and you are measuring 1023mA, you can calibrate the Voltage/Current Bricklet by setting the multiplier to 1000 and the divisor to 1023.

BrickletVoltageCurrent@GetCalibration[out gainMultiplier, out gainDivisor] → Null
Output Parameters:
  • gainMultiplier – Type: Integer, Range: [0 to 216 - 1]
  • gainDivisor – Type: Integer, Range: [0 to 216 - 1]

Returns the calibration as set by SetCalibration[].

BrickletVoltageCurrent@GetAPIVersion[] → {apiVersion1, apiVersion2, apiVersion3}
Returns:
  • apiVersioni – Type: Integer, Range: [0 to 255]

Returns the version of the API definition (major, minor, revision) implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

BrickletVoltageCurrent@GetResponseExpected[functionId] → responseExpected
Parameters:
  • functionId – Type: Integer, Range: See constants
Returns:
  • responseExpected – Type: True/False

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by SetResponseExpected[]. For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

  • BrickletVoltageCurrent`FUNCTIONUSETUCONFIGURATION = 4
  • BrickletVoltageCurrent`FUNCTIONUSETUCALIBRATION = 6
  • BrickletVoltageCurrent`FUNCTIONUSETUCURRENTUCALLBACKUPERIOD = 8
  • BrickletVoltageCurrent`FUNCTIONUSETUVOLTAGEUCALLBACKUPERIOD = 10
  • BrickletVoltageCurrent`FUNCTIONUSETUPOWERUCALLBACKUPERIOD = 12
  • BrickletVoltageCurrent`FUNCTIONUSETUCURRENTUCALLBACKUTHRESHOLD = 14
  • BrickletVoltageCurrent`FUNCTIONUSETUVOLTAGEUCALLBACKUTHRESHOLD = 16
  • BrickletVoltageCurrent`FUNCTIONUSETUPOWERUCALLBACKUTHRESHOLD = 18
  • BrickletVoltageCurrent`FUNCTIONUSETUDEBOUNCEUPERIOD = 20
BrickletVoltageCurrent@SetResponseExpected[functionId, responseExpected] → Null
Parameters:
  • functionId – Type: Integer, Range: See constants
  • responseExpected – Type: True/False

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

  • BrickletVoltageCurrent`FUNCTIONUSETUCONFIGURATION = 4

Callbacks

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by assigning a function to a callback property of the device object:

MyCallback[sender_,value_]:=Print["Value: "<>ToString[value]]

AddEventHandler[voltageCurrent@ExampleCallback,MyCallback]

For further information about event handling using .NET/Link see the corresponding Mathematica .NET/Link documentation.

The available callback property and their type of parameters are described below.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.
